The Florida Fish and Wildlife Conservation Commission claims that 21-year-old Ryan William Waterman violated the Florida Manatee Sanctuary Act. The law makes it illegal to injure, harm, harass, capture or attempt to capture a Florida manatee.

FWC investigators received a tip regarding pictures that Waterman had posted on Facebook. The pictures show Waterman and two young children petting a manatee calf last month in St. Lucie County. They also show Waterman lifting the calf partially out of the water. One image even shows a child sitting on top of the manatee.

Waterman was arrested Sunday and later released on $2,500. Jail records didn't list an attorney.
